We need some information on TSC pin details for imx6ull series processor. where we need to connect X+,X-,Y+,Y-(4 wire resistive touch interface). could you please provide details on that.
Please suggest external IC for resistive touch interface which has linux driver available. we have 2 feet distance from TFT LCD signal to main controller.
Also please let us know how can we do signal condition for those resistive touch signal.
